How does a TDR work? (What is it?)
Time Domain Reflectometer (TDR) is
kind of a 'cable radar'. Like Radar, a signal is sent out, and the round-trip time from
the TDR to the object of interest is measured.
Our little hand-held TDR "Model 50"
can detect a short or open (or the end of the piece of cable) in electrical
transmission lines. For our purposes, we can consider a simple coaxial cable as being an
electrical transmission line. Model 50 launches a signal into the cable. This signal takes
a certain amount of time to travel down the cable. Upon reaching a short or an open in the
cable, part of the signal is reflected back to the instrument. This information is then
used to calculate the distance to the problem. (The time parameter is converted to
distance since we know how fast the signal travels through the cable). Thus
"Time Domain" means the time of the measured parameter, and
"Reflectometry", indicates the instrumentation is looking for reflections from
cable shorts or opens.
PINPOINT CABLE DAMAGE Cables can be damaged during and after
installation. Typically the damaged section is hidden from view behind walls, above
ceilings or buried underground. The Model 50 TDR uses (Time Domain Reflectometry)
technology to quickly identify an open or a short and provide the distance to the problem
location. Additionally, the tone generator feature works with standard tone probes so that
the exact cable path can be traced. MEASURE CABLE LENGTH ON A SPOOL OR INSTALLED.
Our TDR makes it easy for installers to know the amount of cable remaining on a spool or
in a box before pulling a run. When multiple runs are being installed in the same area,
the first run can be measured to accurately determine the total amount of cable required
to complete the job. Checking cable inventory prior to starting a job eliminates unplanned
trips to buy more cable. EASY TO USE. The Model 50 TDR is simple to operate. After turning the
unit on, a cable can be measured or toned with a single push of a button. The full
graphics display provides all the cable management information together on one screen. The
built-in library of over sixty cable types makes finding the correct cable information
easy. The standard banana jack connectors means that different test leads and adapters are
available from many vendors. AFFORDABLE. Telephone and CATV companies have used TDRs to
find cable problems for over thirty years. Until recently, this type of tool cost
thousands of dollars. Advances in technology have allowed the Model 50 TDR to provide the
capabilities of previous TDRs at a fraction of the price. Do
it all with Model 50 TDR the cable
fault finder,
our inexpensive TDR or time domain reflectometer.
Simply select the appropriate cable type...
from the pre-stored
library in the TDR, attach the
leads to two conductors of the cable and with a single press of a button the length of the
cable or distance to an open or short is displayed. Voltage on the wires is continuously
measured and displayed on the TDR to warn of a potentially unsafe condition. The
model 50 TDR will also
inject a tone onto the conductor for tracing cables installed in walls and ceilings with a
standard tone probe like our TT100.
The model 50 TDR " Cable fault Finder" provides
contractors, electricians, low voltage installers, or anyone involved in the installation
or maintenance of metallic cables with the capability to quickly find faults in cables up
to a distance of 2500 feet.
